Question Question 1(d)
(i) Why is the ratio of the velocities of light of wavelengths 4000 Å and 8000 Å in vacuum 1 : 1 ?
(ii) Which of the above wavelengths has a higher frequency? [2]
(i) In vacuum the light of each wavelength travels with the same speed i.e., the speed of light of wavelength of 4000 Å is same as that of light of wavelength 8000 Å.
(ii) The light of wavelength 4000 Å will have higher frequency.
